Carbon capture and sequestration CCS is surely a useful

Of all these materials, TiO2 photocatalysts with a band gap Tiopronin of 3.2 eV have been shown to be the most convenient candidates for this application, due to their charge carrier properties. However, their lower catalytic efficiency and product selectivity are the key challenges to CO2 conversion for fuel applications. For these reasons, there has been a huge effort in this area to develop highly efficient and promising catalysts for improved selective products.
